Like many here, I find myself in the situation where I would love to contribute to Swift, but lack the time and/or skillset to do so. To give an example: As a lecturer, I would love nothing more than to promote Swift as a primary language in CS education. Unfortunately, that's not possible at the moment, due to several issues. Even though I cannot solve these issues myself, I would gladly donate to see them resolved.
If we really want to see our favorite language succeed in the outside world, we need much better cross-platform support, cross-platform tools, and so on. We cannot expect Apple to fund this, nor should we hope that some benevolent developer will offer up all his/her free time.
It would be great if Swift had a Foundation (like many other open source projects) that could accept our donations and use these to fund work the community needs. Has this ever been discussed?
